OFweek lithium in "intelligent manufacturing" network under the background of manufacturing technology, the traditional power battery orders dispersed development pattern is difficult to meet the high quality requirements of the power battery market. Only aiming at high precision, fully automated and intelligent production line can meet the dynamic demand of new energy vehicles in the future.
Battery enterprise power production line automation intelligent manufacturing is falling from the concept of "concept"
Issued by the State Ministry of the "intelligent manufacturing pilot demonstration of 2016 special action plan" put forward clearly, focusing on the selection of more than 60 intelligent manufacturing pilot demonstration projects, the formation of a number of key areas of intelligent manufacturing standards, the development of power battery industry ushered in a hitherto unknown opportunity.
With the new energy vehicles for battery safety increasingly stringent requirements, traditional manufacturing process has been difficult to meet the requirements of battery consistency, it will be replaced by the intelligent automatic production line and assembly line, must upgrade power battery production enterprises.
It is a convenient path to make up the smart manufacturing of power battery short board
Tesla Howe threw $5 billion in the battery superplant Gigafactory to achieve the target of 35GWh production by 2018. The super factory power battery production line is highly automated, and a large number of high-tech robots are used in the factory. For example, as long as these robots use digital maps, they can cruise in the factory freely and detect the surrounding environment with sensors. This reflects from the side that the frontier technology and production mode of the power battery in foreign countries are far more than the domestic.
China's power battery enterprises have the largest number and the largest production capacity, and have formed a more perfect industrial chain system. They have mastered the formulation design, structural design and manufacturing technology of power battery, and the production line has also been gradually changing from semi-automatic to full-automatic large-scale manufacturing. But we need to wake up to the fact that there is still a big gap between domestic power battery enterprises and advanced foreign enterprises in terms of high-end materials and related basic research, as well as battery safety, reliability and system management technology.
Whether from the national strategic planning level, or improve product quality, shoulder to shoulder, the United States, Japan and South Korea, or reduce business costs, increase business revenue and other aspects, all the domestic power battery industry needs to achieve "intelligent manufacturing" as soon as possible.
The industry generally believes that even if the power battery capacity is overcapacity in 2017, the surplus is still low - end production, and the real high-end products will still be in short supply. For power battery, the increase of monomer specific energy is only one aspect of superior performance, and more importantly, the high consistency of all single cell batteries, just like "barrel principle", and the dynamic performance of the whole vehicle is determined by the worst battery or battery pack. In order to improve product consistency, large-scale intelligent production is essential.
Through strict control of the production environment, many aspects of reducing human contact and control production precision, can improve the overall quality of domestic battery products, and intelligent production differences is also the domestic enterprises and foreign enterprises battery battery products are an important reason for the gap.
Bian Shuguang, deputy director of the hi tech research and development center of the Ministry of science and technology, believes that improving the level of intelligent manufacturing of power batteries and improving verification testing methods and standard system is the key task of China's power battery development.
Three dimensions of innovation break through the traditional battery manufacturing mode "Besieged City"
Analysis of industry experts, whether material or production of lithium batteries, domestic enterprises are still facing low degree of automation, low production efficiency, low product yield, low efficiency of information interoperability.
Taking positive materials as an example, many factories have low intelligence level and high level of human participation, so it is difficult to realize the rapid and intelligent production line.
This leads to the domestic lithium cathode material is more than 40% of global market share, but the supply is mostly below the average quality of cathode materials, with the most outstanding problems facing the development of cathode materials of enterprises is the product quality and production capacity of the industrial convergence. In this context, the establishment of positive material intelligent factory is of great practical significance. By realizing automatic control of key processes in production process line, we can achieve transparent and shared manufacturing information and management information throughout the process.

For the problems facing the production of positive materials, the upgrading of power battery manufacturing is more urgent and the situation is more complex. As the core parts of the new energy vehicle, how to quickly improve the performance index and reduce the production cost has become the core proposition of the whole industry.

In fact, the main problem facing the domestic power battery manufacturing is that most of the power battery devices can only achieve automation in some sections, and there is still a great distance from automation and information technology. The data platform on many devices is still not built. The whole power battery production process control has not yet formed a complete specification and standard, including many factors such as incoming material, humidity, pole piece tension and so on. All these factors are in an uncontrollable state, which directly leads to a low level of production efficiency and product yield.
Large scale production of power battery will be an inevitable trend. For domestic power battery enterprises, intelligent manufacturing is the only way to upgrade and get rid of traditional manufacturing mode of "Besieged City".
According to the analysis of industry experts, intelligent manufacturing can start from the dimensions of technological innovation, organizational innovation and pattern innovation. First, technological progress is the key factor in the development of advanced manufacturing. Since the middle of last century, the development of science and technology has entered an era of change rapidly, the development of electronic information technology and automation technology rapidly, the information technology represented by the Internet revolution has injected new vitality for the manufacturing industry, power battery industry also should be good at using computer integrated manufacturing, agile manufacturing, virtual manufacturing technology.
Secondly, the innovation of organization mode is the soul of advanced manufacturing development. In recent years, the diversification of the market demand forced the manufacturing industry to many varieties, small batch, shorten the production cycle of the direction of evolution, rigid manufacturing mode is gradually replaced by flexible manufacturing mode, the power battery production organization and the corresponding, have evolved from the pyramid hierarchy management to flat, matrix management direction.
Thirdly, "intelligent manufacturing" is not the concept of being born out of the world. Instead, it is based on its internal development logic and evolved through long-term evolution. It can be said that the intelligent manufacturing power battery with the change of market demand, the integration of advanced manufacturing technology innovation, system innovation and organization innovation mode, integrated manufacturing, lean production, agile manufacturing, virtual manufacturing, network manufacturing and other advanced manufacturing system and mode.
From the three dimensions of technological innovation, organizational innovation and mode innovation, we can understand that the intelligent manufacturing of power battery is conducive to better grasp the current position of power battery manufacturing industry and the direction of future efforts, so as to avoid blindly seeking new and eager for success.
